INA181A3IDBVR Description

Short technical summary and product information.

The INA181A3IDBVR from Texas Instruments is part of the INAx181 family of bidirectional, current-sense amplifiers. These devices are designed for cost-optimized applications and are capable of sensing voltage drops across current-sense resistors at common-mode voltages ranging from -0.2 V to +26 V, independent of the supply voltage.

 

Key electrical specifications include a high bandwidth of 350 kHz, a maximum offset voltage of ±150 µV at 0 V common-mode, and a gain error of ±1% maximum. The amplifier also features a 1-µV/°C maximum offset drift and a quiescent current of 260 µA maximum.

 

This specific device, the INA181A3IDBVR, comes in a 6-pin SOT-23 package. It operates within an ambient temperature range of -40°C to 125°C. The amplifier is suitable for applications requiring accurate current monitoring in a compact form factor.

 

Designed for integration into various systems, the INA181A3IDBVR provides a reliable solution for current sensing needs. Its bidirectional capability and wide common-mode voltage range make it versatile for both low-side and high-side sensing configurations.
